You must use the Periodic Table. Metals, on the right side, will be positive. Non-metals, left, are negative. You need to know the specific ionic charge elements.
Answer:
The Gulf Stream is influential on the climate of the Florida peninsula.East winds moving over this warm water move warm air from over the Gulf Stream inland, helping to keep temperatures milder across the state than elsewhere across the Southeastern United States during the winter.
Explanation:
hope this helps!
The formula to determine the wavelength is, De-Broglie wavelength formula:
-(1)
where, is wavelength, m is mass, v is velocity and h is Planck's constant = =
mass, m = 147 g (given)
Since, 1 g = 0.001 kg
So, 147 g = 0.147 kg
v = 91.0 mph (given)
Converting mph to mps:
Since,
So, =
Substituting the values in formula 1:
Hence, the wavelength wavelength of a 147-g baseball traveling at 91.0 mph is
.
Answer:
Impact resistant containers that can withstand the extremely low temperatures should be used. Materials such as carbon steel, plastic and rubber become brittle at these temperatures. Only store liquid nitrogen in containers with loose fitting lids (Never seal liquid nitrogen in a container).
You didn't send a picture. But the activation energy is always the difference between the starting point and the highest point in the graph
